Method for separation of rare earth ion
A method for identifying and separating a rare earth ion. The method includes bringing one or more rare earth ions into contact with a mineralization agent capable of mineralizing the rare earth ions, wherein the one or more rare earth ions are separated as rare earth minerals, based on a mineralization tendency of the mineralization agent with respect to a rare earth ion series.
1. An artificial peptide comprising a peptide region having the amino acid sequence selected from the group consisting of SEQ ID NOs: 4-7, 16, 17, and 31-34.
2. A method for separating a rare earth ion, the method comprising:
bringing one or more medium and/or heavy rare earth ions into contact with a mineralization agent comprising a peptide region having the amino acid sequence selected from the group consisting of SEQ ID NOs: 4-7; or
bringing one or more heavy rare earth ions into contact with a mineralization agent comprising a peptide region having an amino acid sequence selected from the group consisting of SEQ ID NOs: 16 and 17; or
bringing one or more rare earth ions into contact with a mineralization agent comprising a peptide region having the amino acid sequence selected from the group consisting of SEQ ID NOs: 31-34,
wherein the one or more rare earth ions are separated as rare earth minerals, based on a mineralization tendency of the mineralization agents with respect to each rare earth ion series.
3. The method according to claim 2 , comprising:
bringing one or more medium and/or heavy rare earth ions into contact with a mineralization agent comprising a peptide region having the amino acid sequence of SEQ ID NO: 4; or
bringing one or more heavy rare earth ions into contact with a mineralization agent comprising a peptide region having the amino acid sequence of SEQ ID NO: 16; or
bringing one or more rare earth ions into contact with a mineralization agent comprising a peptide region having the amino acid sequence selected from the group consisting of SEQ ID NOs: 31-34.
4. The method according to claim 2 , wherein one or more rare earth ions are separated as the rare earth minerals from a mixture of two or more rare earth ions.
5. The method according to claim 2 , wherein one or more light rare earth ions are separated.
6. The method according to claim 5 , wherein a neodymium ion is separated.
7. The method according to claim 2 , wherein one or more heavy rare earth ions are separated.
8. The method according to claim 7 , wherein a dysprosium ion is separated.
9. The method according to claim 2 , wherein one or more light rare earth ions are separated from one or more heavy rare earth ions.
10. A method for detecting a rare earth ion, the method comprising:
bringing one or more medium/and or heavy rare earth ions into contact with a mineralization agent comprising a peptide region having the amino acid sequence selected from the group consisting of SEQ ID NOs: 4-7; or
bringing one or more heavy rare earth ions into contact with a mineralization agent comprising a peptide region having the amino acid sequence selected from the group consisting of SEQ ID NOs: 16 and 17; or
bringing one or more rare earth ions into contact with a mineralization agent comprising a peptide region having the amino acid sequence selected from the group consisting of SEQ ID NOs: 31-34,
wherein the one or more rare earth ions are separated as rare earth minerals, based on the mineralization tendency of the mineralization agents with respect to each rare earth ion series, and the rare earth minerals or rare earth species in the rare earth minerals are detected.
11. The method according to claim 10 , comprising:
bringing one or more medium and/or heavy rare earth ions into contact with a mineralization agent comprising a peptide region having the amino acid sequence of SEQ ID NO: 4; or
bringing one or more heavy rare earth ions into contact with a mineralization agent comprising a peptide region having the amino acid sequence of SEQ ID NO: 16; or
bringing one or more rare earth ions into contact with a mineralization agent comprising a peptide region having the amino acid sequence selected from the group consisting of SEQ ID NOs: 31-34.
